Forthcoming Conferences


The 27th European Colloquium on Heterocyclic Chemistry (ECHC 2016);
http://www.ldorganisation.com/v2/produits.php?langue=english&cle_menus=1238916009.

This traditional meeting with a famous history will be held in the beautiful Beurs van Berlage, in the city center of Amsterdam, from July 3 to July 6, 2016. The ECHC2016 covers the field in its full range, from Organic Synthesis, Materials and Catalysis to Chemical Biology and Medicinal Chemistry. We have a great line-up of world renowned speakers.


The 9th Balticum Organicum Syntheticum conference (BOS2016) will take place July 3-6, 2016. in beautiful Riga, Latvia. Further details on schedule and registration are at: www.boschem.eu. We expect conference registration fees to be covered by InnovaBalt. Topics include medicinal, organic, catalytic, and other topics of interest to chemists.


15th Belgian Organic Synthesis Symposium
July 10-15, 2016 - Antwerp, Belgium

The conference will cover a broad range of timely subjects in the field of organic chemistry. One of the major aims of the BOSS symposia has always been to give young chemists the possibility to attend a high level conference at a reasonable cost, instead of only addressing a small group of highly specialised chemists.

Future Conferences


The 26th International Society of Heterocyclic Chemistry Congress will be held in Regensburg, Germany, 3 to 8 September 2017.


The 18th Florida Heterocyclic and Synthetic Conference (FloHet-2018) will take place at the University of Florida, Gainesville, 4 to 7 March 2018.
